MiniProf BT is based on secure full-contact measurements and has a knife-shaped full contact point directly to the surface of a given profile. The magnetic full contact point minimizes influences from oil, lubrication, dirt and other substances on the profile as it “cuts” through the layers. It ensures constant contact to the actual profile during the complete measuring process and minimizes operator influence.

The accuracy of a MiniProf BT system is very consistent due to the unique measuring principle with a small magnetic measuring wheel and two rotating optical high resolution encoders which ensure that the measurement is performed perpendicular to the surface of the entire profile.

Due to the unique combination of full contact measurements, consistency and outstanding high-resolution optical encoders, MiniProf BT provides the highest accuracy available on the world market today. 20-30.000 collected individual points in one single profile measurement generate outstanding raw material resulting in excellent profile measurements with extremely high accuracies.

Full contact vs. non-contact

Layers on surface

Actual profile

Full contact byNon contact

A full contact measuring system measures the exact profile. Concerns about dirt, oil and greasy surfaces are minimized thanks to the MiniProf BT full contact point which cuts through unwanted layers on the profile.

A non-contact measuring system is not in full contact with the actual profile and therefore provides pictures of a given surface including unremoved dirt, oil etc.

Full contact measuring systems are not influenced by reflecting light on the profile surface or by shiny profile surfaces like a newly turned wheel etc.

Non-contact devices may show inconsistency when used on reflecting surfaces, in bright sunlight, frost, fog and moist climates etc. due to the sensibility of the non-contact data collecting method.

The MiniProf BT TwinHead Rail and MiniProf BT TwinHead Wheel systems are portable wireless instruments designed to produce fast and exact measurements of track and rolling stock. Opposed to normal single head instruments, the TwinHead measures both left and right profile together, obtaining a highly accurate relationship between the two profiles. This is especially important in analyzing running characteristics for rolling stock using for instance equivalent conicity studies.

The system consists of two measuring heads on a fixed beam. The two profiles are measured consecutively one by one. Each profile measurement will be done as by the single-head system. The measurements are stored on the computer and are accessible as individual profiles and together in pairs in one common coordinate system.

This provides a high accuracy on the gauge and a precise knowledge of any rotation of the profiles with respect to each other. This information is only possible to gather if you measure with a TwinHead instrument and is a crucial part of any wheel/rail interaction study.

The TwinHead system includes extra software modules for MiniProf Envision, namely TwinHead Package and MiniProf Contacts for doing Equivalent Conicity analysis.
